Patent DE-102010051102-A1 (DE)
Title: Device, useful for ultrasound guided puncture, comprises sonic probe surrounded by casing and ultrasonic transducer, and probe is covered in region of the sound outlet with gel-forming sound-conducting glucosaminoglucan
IPC: A61B8/00

Abstract: Device comprises a sonic probe and an ultrasonic transducer, where the sonic probe is surrounded by a casing, which is covered in the region of the sound outlet with a gel-forming sound-conducting glucosaminoglucan, which is crosslinked by bifunctional or trifunctional molecules with formation of linkers and is bonded chemically and covalently with the casing by bifunctional molecules with the formation of linkers. At least one hose opens into the interior of the casing, or a device opens for removing gas, which is connected to a suction device and to a manometer. Independent claims are also included for: (1) a compound obtainable by reaction of a free hydroxyl or a free amino group of the conductive Gel forming glucosaminoglucan with a free isocyanate group, carboxyl group, carboxylic acid halide-group, ester group, alkylene carboxy-group, epoxy group, amino group or hydroxyl group of sonic probe cover to form a linker; (2) producing a ligation product, comprising oxidizing the aldehyde group of glucosaminoglucan, polysaccharide or sonic probe cover-forming film and subsequently reacting the oxidations product with polysaccharide or glucosaminoglucan, where the connection between glucosaminoglucan and polysaccharide or sonic probe cover-forming film is an amide bond; (3) a ligation product in that the starting material for the linker comprising linear or branched, optionally saturated, aliphatic or alicyclic 1-22C, preferably 3-8C hydrocarbon groups, aryl group with 5-12C, preferably 6C, aryl-1-4C-alkyl, and aryl-2-6C-alkenyl groups, which can be substituted with the 1-6C-alkyl and/or 2-6C-alkoxy groups, or heteroaryl, heteroaryl-1-4C-alkyl- and heteroalkyl-2-6C-alkenyl groups with at least two hetero atoms including nitrogen, oxygen and sulfur, which is substituted with 1-6C-alkyl and/or 2-6C alkoxy group, where the linker functional groups include a film of the sonic probe cover for forming the covalent bonds with glucosaminoglucan and/or linker, and the functional groups include hydroxyl, amino, carboxyl, isocyanate, carboxylic acid halide (halide is chloride, bromide and/or iodide), carboxyalkylene derivative of formula (-(CH 2) q-COOH), or ester group of formula (-COOAlk); (4) a device for controlling ultrasound-controlled puncture of the human or animal body by light signals, where the position and the projection of light source inserted on the sonic probe is controlled by at least one processor which is replaced both by the ultrasonic transducer and by the surgeon information; (5) a device for improved handling of an expansion body by stretching body pushed via a puncture needle, where the stretching body is provided with a spring and a holding mechanism, which freely holds the tip of the puncture needle by the stretching body or holds it in pushed forward manner by the tip of the puncture needle; and (6) a device for improved handling of guide wires, where differently crafted ends of the guide wire of a U or spiral shaped, rotated casing are pushed forward. q : 1-10; and Alk : 1-7C alkyl.
